Today's most popular blockchain application is centralized exchanges. The main use case is to send fiat, play with the markets and then hopefully withdraw more fiat than you put in. The improvement over traditional online gambling is minimal. The Silk Road, which kickstarted Bitcoin adoption, brought a much more interesting improvement over the status-quo. Suddenly, acquiring illegal drugs was easy and safe(r). That was the Napster of blockchain. We will talk about blockchain again when a similarly disruptive use case is found/created. We're missing a couple of crucial pieces of infrastructure before the "people's money" use case can even be put to the test (decentralized fiat on ramps, convenient wallets, scalable price stability, fast confirmations).
